Stock analysis and suggestions through scraping

stocks_app - Development Branch

Git Instructions

• All changes will be made here
• DO NOT merge to/from master, under any circumstance.
• Always work on the dev branch

git checkout -b "dev"
git fetch --all --prune
git pull origin dev --rebase # ALWAYS use the --rebase option to avoid unecessary *pull* commits

Installation and Running

• To install the dependencies

mkvirtualenv stocks_app --python python3.6
pipenv install
workon stocks_app

• Optionally, you can use direnv. It loads various environemnt variables and (in this case) python environment(s) directly on cd-ing. The .envrc file has already been included. (Mind you, you will still have to install the environment as stated above, but will not need to manually workon stocks_app everytime you work on the project)

sudo apt install direnv
echo  'eval "$(direnv hook zsh)"' >> ~/.zshrc
source ~/.zshrc
cd $PROJECT_DIR
direnv allow

Database

Setup

• We will be using postgres for the database. Postgres enables a lot of additional fields (JSONField, HStoreField, NumericRange, etc) that make storage and manipulation a lot easier.
• You will have to create a postgres user called test, underwhich a database called stocks, password: test12345.
• Keeping common credentials may involved slight more work initially, but later will help avoid unnecessary conflicts in the settings.py file.

$ sudo apt install postgres
$ sudo -u postgres -i
postgres> psql
postgres=# CREATE USER test with PASSWORD 'test12345';
postgres=# ^C
postgres> createdb stocks_app --password --owner=test
postgres> logout

• Once you've set this up, you should be good to go. After we begin hosting, we will be migrating to a centralized database with the same credentials; this initial setup will enable you to migrate by just changing the HOST in the database configuration.

Migrations

• Make the initial migrations (along with the single committed one) for the administrative tables and postgres special field support

./manage.py makemigrations
./manage.py migrate
